Faulty website and delivery 10 days earlier than booked

Selected Australia but when entering address. Help line said he would call me back in 10minutes - it took hrs to tell me the website is faulty but I should use it as it will be processed. Placed order for delivery on 23 August for a 70th birthday and paid nearly R1,500. The bouquet was delivered on 13 August! After complaining, I was told ANOTHER bouquet will be delivered on the date I requested. How stupid. I look like a complete idiot sending flowers 10 day early!
